I know that the Microsoft Edge browser is still in development, but when I log into Forms with it and go to Manage, it flashes the regular page at me and then gives me a blank page with just the navigation and search bars. If I hover over the white space, I can see that the links are still there. Other items seem to be working correctly so far.
When viewing the Answers site I am also not able to see any of the forms that can be filled out.
UPDATE: I can see forms when looking at an actual post, but not in categories on the Answers site.
